Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule.
Elements are substances that are made from one type of atom. An element cannot be broken down into any other substance. While compounds are substances made from atoms of different elements joined by chemical bonds. And mixture is made by simply mixing together elements and compounds. Therefore, the answer is letter c. mixtures.
